Improved genetic counseling in Alport syndrome by new variants of COL4A5 gene

Nephrology (Carlton). 2015 Jul;20(7):502-5. doi: 10.1111/nep.12486.

Abstract

There are current requirements of using genetic databases for offering a better genetic assistance to patients of some syndromes, especially those with X-linked heredity patterns (like Alport Syndrome) for the high probability of having descendants affected by the disease. We describe the first reported case of COL4A5 gene missense c.1499 G>T mutation in a 16-year-old girl confirmed to be affected by Alport Syndrome after genetic counseling. Next Generation Sequencing procedures let discover this mutation and offer an accurate clinical treatment to this patient. Current scientific understanding of genetic syndromes suggests the high importance of updated databases and the inclusion of Variant of Unknown Significance related to clinical cases. All of this updating could enable patients to have a better opportunity of diagnosis and having genetic and clinical counseling. This event is even more important in women planning to start a family to have correct genetic counseling regarding the risk posed to offspring, and allowing the decision to undergo prenatal testing.
